I am planning to purchase a new automatic car in the next 6 months, with an on-road budget of ₹20 lakh in Bangalore. I am preferably looking for an SUV with a 5-star safety rating and a large boot of around 500 litres. I like the Tata Sierra, but am wary of its new naturally aspirated petrol engine paired with a DCA automatic. My annual running is low at around 7,000km, with about 30% highway usage. I understand that my usage does not ideally suit a diesel, but I am still interested due to the mileage and torque benefits. My main concern with diesel engines is DPF issues, given my low running. Do the Sierra or other Tata diesel cars face DPF issues with limited highway use? Are there any better alternatives that suit my requirements?

The Tata Sierra is a very appealing car and definitely worth considering. We have driven the 1.5-litre naturally aspirated petrol with the DCA automatic, and while it is smooth, it feels sluggish, especially on the highway. Quick overtakes of fast-moving trucks require planning and effort.
Given that around 30% of your driving is on highways, we would recommend a diesel car instead. It is torquey, has a strong mid-range, and is much better suited to overtaking and relaxed long-distance driving.
Regarding DPF concerns, the issue is not low annual mileage but driving pattern. Diesel particulate filters need the car to be driven at steady speeds for some time to clean themselves. Since you do have regular highway usage, your driving pattern should allow the DPF to regenerate properly, making clogging unlikely in normal use.

I am planning to buy a new petrol car with a manual gearbox. My budget is around ₹13 lakh. My usage will be 70% city and 30% highway. Could you please suggest SUV options within this budget?

With a daily running of around 50 to 60 km, a diesel automatic makes good sense as your monthly usage will easily justify the better fuel efficiency and relaxed nature of a diesel engine.Between the two options, the Kia Seltos diesel automatic is the better choice overall. The diesel engine is refined, and the 6-speed torque converter automatic is smooth and well-suited for normal city traffic as well as highway drives.The Tata Sierra is also a strong Midsize SUV with more cabin space. But its diesel engine is noticeably noisier and less refined than the Hyundai-Kia diesel. It is also over a lakh more expensive in comparable automatic variants.For your usage and preference for an automatic, the Seltos diesel automatic is the more balanced and sensible option thanks to its refinement, smooth gearbox and lower price.

I currently own a 2018 Honda WR-V diesel manual (6-speed), which has run about 50,000 km, along with a Tata EV purchased in 2023, which has covered around 20,000 km. I have now decided to replace my WR-V with a BS6 diesel automatic car. Could you please suggest which diesel automatic model would be the best choice according to Autocar?

Without knowing your budget and more requirements, we can't recommend the ideal choice for you. We have shortlisted models that you should consider, and why they are of interest. Compact SUVs- Hyundai Venue: (+) Smooth diesel engine and auto gearbox combo, good interior space, upmarket interior | (-) Expensive for its size- Kia Sonet: (+) Smooth diesel engine and auto gearbox combo, upmarket interior, good value | (-) Rear seat space is limited, due to be replaced in the coming year Midsize SUVs- Kia Seltos: (+) Spacious interior, well equipped, good ride comfort | (-) Performance is adequate only- Tata Sierra: (+) Class-best space, feature-packed, tough build, ride comfort | (-) Engine feels noisy, road noise- Hyundai Creta: (+) Well equipped, decent performance | (-) Due to be replaced in the coming year

I am confused between the Mahindra XUV 7XO AX5 and Mahindra XUV 7XO AX7 variants, as I prefer practicality over extra features. Alternatively, should I consider waiting for the Tata Sierra?

If you don't mind the additional spend, we'd recommend the Mahindra XUV 7XO in AX7 trim. Elements like its larger 18-inch alloy wheels and leatherette upholstery add greatly to the look and feel of things. While auto climate control, a 540-degree camera and front parking sensors are features you will appreciate every day. The Tata Sierra is not a like-for-like alternative to the Mahindra 7XO. The 7XO is larger, more powerful and also offers three rows of seating.Further, the 7XO is slightly pricier, too. Within Tata's range, the Tata Safari is an alternative to the 7XO.
